Williams Museum of Papermaking houses hand papermaking artifacts from around the world. Dard Hunter, a renowned paper historian and founder of the museum, collected many of these objects throughout the early 1900s as he sought to gain more knowledge about this craft. Nearly 100 years later, the museum continues its mission to collect, preserve, increase, and disseminate knowledge about papermaking to the general public. By collaborating with Georgia Tech researchers, and the larger Atlanta community, by using scientific tools, we can unlock hidden information held within the objects, both from a historical and scientific perspective. Recently, two Georgia Tech Postdoctoral Fellows, Nasreen Khan (Paper Museum\/RBI) and Daniel Vallejo (School of Chemistry and Biochemistry) sought to uncover more about a loom in the museum\u2019s collection, connected with the history of the Indian subcontinent and Gandhi.\u003C\/p\u003E\u003Ch5\u003E\u003Cstrong\u003EDard Hunter and Background of the Loom\u003C\/strong\u003E\u003C\/h5\u003E\u003Cp\u003EIn the 1930s, Dard Hunter traveled to Asia and the Indian subcontinent (I.e., India, Pakistan, Bangladesh, Kashmir) to document hand papermaking techniques and collect tools and paper samples.\u0026nbsp;At that time many people, including Mahatma Gandhi, aimed to revitalize the Indian hand papermaking tradition by supporting and creating schools to teach the craft [1-3]. Dard Hunter visited several papermaking villages and schools, including those helped founded by Gandhi. Hunter brought a loom back to America that was used to weave a chapri (paper-mold cover or screen), but the information of the specific origins of this loom was lost.\u003C\/p\u003E\u003Ch5\u003E\u003Cstrong\u003EWhat\u2019s Missing?\u003C\/strong\u003E\u003C\/h5\u003E\u003Cp\u003EWhile Hunter and other researchers documented and studied hand papermaking tools and materials of this region and time, it was primarily from a historical and cultural perspective [1-5]. Much of their focus has been on the plant materials used to make the paper and molds [1-5]. However, some parts of the handmade molds in Asia were known to also use biological materials sourced from animals, such as silk and animal hair [1-4]. Since the exact origin of the loom and the fibers used to construct the paper mold was not known, the museum was interested in learning more about this object.\u003C\/p\u003E\u003Cp\u003EWith scientific tools, the study aimed to understand more about the fibers commonly used in traditional handmade paper-mold covers in the 1930s Indian subcontinent by using scientific tools. With the availability of high-resolution microscopy technologies and historical documentation at Georgia Tech and the Museum, researchers aimed to either prove or disprove whether the origin of preserved fibers on the loom was from an animal and determine with historical context where the loom was acquired.\u003C\/p\u003E\u003Ch4\u003E\u003Cstrong\u003EWhat we did and what we discovered\u003C\/strong\u003E\u003C\/h4\u003E\u003Ch5\u003E\u003Cstrong\u003EAre the Fibers Really Horsehair?\u003C\/strong\u003E\u003C\/h5\u003E\u003Cp\u003EIn forensic analysis, typically the first step to identify unknown fiber or hair samples is to conduct microscopy. Microscopy, or the science of using microscopes to view samples \u0026amp; objects that cannot be seen with the naked eye, is the gold standard for analyzing and identifying unknown fibers by comparison to a library of known reference materials. This is possible because hair from different sources or animals have different \u201cmorphologies\u201d, or physical features, that help identify their origin.
